Rolling MixedEasyQuestion 6176

Question

A hollow sphere has higher MI than solid sphere (same M, R). When rolled down incline:
  1. A
    Hollow sphere is faster
  2. B
    Solid sphere is faster
    Correct
  3. C
    Both same
  4. D
    Depends on angle

Correct answer

Solid sphere is faster

Explanation

Lower I/MR² → less KE in rotation → more in translation → faster. Solid (2/5) < hollow (2/3). Solid sphere is faster.
